I have an old 4.5.2 version of umbraco that I am intending in trying to get it to umbraco 7.

Having read https://our.umbraco.org/documentation/getting-started/setup/upgrading/version-specific

and

http://code.leekelleher.com/umbraco/archive/

and

http://www.blix.co/blog/2014/6/5/follow-the-path-upgrading-umbraco-from-v4-to-v7.aspx

I can see my starting point is getting it to 4.6.1 but all the info I can find starts at 4.6.1 or above. Is there any thing specific I need to do to get it from 4.5.2 to 4.6.1?

Thanks for any help and sorry if I've missed the information.
